Synthesis and self-assembly of PMBTFVB-g-PNIPAM fluorine-containing amphiphilic graft copolymer

This article reports the synthesis of an amphiphilic graft copolymer containing a perfluorocyclobutyl (PFCB) aryl ether-based backbone and poly(N-isopropylacrylamide) side chains by a combination of thermal step-growth cycloaddition polymerization and atom transfer radical polymerization (ATRP).

Fluorinated enol ethers: their synthesis and reactivity

This review sums up the methods for the preparation of fluorinated enol ethers as well as their numerous synthetic applications.

High Performance and Multipurpose Triarylamine-Enchained Semifluorinated Polymers

Transparent, film-forming fluorinated arylene vinylene ether (FAVE) polymers with enchained triarylamine (TAA) moieties were prepared and characterized. Control over fluoro-olefin content within the backbone, as a function of base, was confirmed and postpolymerization dehydrofluorination was shown to increase fluoroolefin content from 5 to 31 mol %. Thermal cross-linking was found to occur approximately 100 °C lower than in traditional FAVE polymers (ca. 160 °C). Electrochemical analysis demonstrated the enchained TAA retained its established electrochemical character. The latent reactivity of the TAA was explored via electrophilic aromatic substitution and formylation reactions toward precise functionalization for specific electro-optic applications and others.

Sulfonated Fluorovinylene Aromatic Ether Polymers for Proton Exchange Membranes2

A new semi-fluorinated perfluorocyclobutyl (PFCB) aryl ether containing polymer was prepared in high yield via the condensation of a commercial 4,4'-((1,2,3,3,4,4-hexafluorocyclobutane-1,2-diyl)bis(oxy))bisphenol (bisphenol T) and bis(trifluorovinyloxyether)biphenyl producing transparent, flexible films. The polymer system was structurally characterized using 1H and 19F NMR and exhibited a high degree of thermal stability as determined by thermogravimetric analysis capacity. The sulfonated analogue showed the highest degree of sulfonation at 27% from ion-exchange chromatography, producing a conductivity of 0.011 S cm-1 at 100% relative humidity.
